Richard Garfield Flash (born 8 April 1976) is an English former footballer, whose career was hampered by knee injuries.

Flash was born in Birmingham. As a schoolboy he was scouted by Liverpool, Arsenal, Aston Villa and Manchester United; Manchester United scout Geoff Watson persuaded him to sign schoolboy forms, and he went on to captain United's West Midland youth team, the Manchester Eagles, for three years, winning the Keele Classic at under-14 level. In 1990 he turned down the opportunity to move to the F.A's National School of Excellence at Lilleshall to train locally with Aston Villa and Birmingham City, in addition to Manchester United. However, an injury to his right knee at age 14 hampered his development.

In 1992 he joined the ranks at Manchester United with Michael Appleton, Terry Cooke, David Johnson and Jovan Kirovski. During his seven-year club career, he played at youth team and reserve level and was room-mates with David Beckham and Terry Cooke. However, he had injured his right knee when he was 14, and early in his Manchester United career he sustained a second dislocated right patella which forced him onto the sidelines for two years.
